This invention relates 't'ijgrillesfr use in Windows, doors and'the likewhich will be neat in appearance and ine'iipen'si'v'e in manufacture andin which it will be adjustable in its width to fit a wide range of dooror windcw openings.

The further object is to provide a grille that will have a planar sidebetweehth frame to pass over stiles or paneling as in doorsmrithoutinterference, and to provide holes in the frame'of the grille in twodirections at right angles to each other for the passage of nails orscrews in either direction for the fastening of the grille according tothe requirements of the window or door.

I accomplish the above and other objects which will hereinafter appearby the mechanism illustrated in the accompanying drawing, in which Fig.l is a View in side elevation of my grille, with one of its adjustableends at its innermost limit and with the other end at its outermost limtof adjustment, the top horizontal and adjustable frame member beingbroken away in part and sectioned to show the inner frame member;

Fig. 2 is a fragment in section on the line 22 of Fig. I lookingiri'thedirection of the arrows;

Fig. 3 is a like section on the line 3-3 of Fig. 1; V f

Fig. 4 is a detail in section on the line i l of Fig. 1; and

Fig. 5 is an end elevation of the grille looking in the direction of thearrow 5 in Fig. 1.

Like characters of reference indicate like parts in the several views ofthe drawing.

The grille filler 6 comprises a series or parallel horizontal rods 1,which are welded, soldered or otherwise fastened to a plurality ofvertical rods 8 all laid on the same side of the rod assembly '1.Similar rods 9 (see Fig. 2") are laid at right angles to the rods 8 onthe opposite sides of rods 8 from rods I, and are welded, soldered orotherwise fixed to the rods 8, there being one red 9 so secured to rods8 at each end 'of said 'rods' on top and bottom of the filler 6.

The vertical rod 8 at the ends of the horizontal rods 1 are on the sameside as the rods'8. The ends of the rods 1, opposite the mass, arecovered by a narrow flat strip of metal 8" looped over the rod ends andsoldered to the ends and to ShdWi'lifi Fig; 2', I'ISZV corrugations Hextend in'g longitudinally oronejof said flanges on each tube. One ofthese tubeslfl is s'lip'ped ndwise on the wire rods '9 which enter acorrugation II with the ends of rods 8 iiith split between the flangesof the tubes. The ends of rods 8 may be welded or otherwise fasteh'd'toth'tube if desired but in'practice the withdrawal df the'tube's I0 isprevented by friction. This completes the structure of the filler 6. Thetubes H] in practice are formed out of metal strips.

The grille is made adjustable ill width, or herizontal direction, byproviding the filler with adjust'able ends [2, l2. As the two ends 12are alike iii construction and operation, except one is in reverse orderto the other, 'a description of one will s'uhice' for both. j'

A series of rods I3, one for each rod 1 bf the filler, is passed acrossthe inner side of its adjacent rod 8 under the loop of strip 8andacro'ss' the inner side of the'next vertical rod 8, and withdrawal isprevented by the inner ends of the rods l3 being bent in a loop aroundtheir adjal5, split along onesiae and having flanges with a corrugationor channel IS in one of the flanges, as described for tub'elll, is slidover wire is and the ends of rods 13 as shown in Fig. 4. To each end .ofthe tube I5, short tubes I! and [8 are welded, 'andslide over theiradjacent tubes lil as shown in Figs. 1, 2 and 3. The tubes H and I8 aresubstantially of the same length as the rods l3. v

The ends of the tubes l5 are extende past tubes l1 and I8 and haveperforations l9 and 20 at right anglesto each; other for the passage ofnails or screws used in fastening the grille to window or'dodrfth'e twodirections" being alternate ones for use according to the support towhich the grille isfastened.

In the operation of my invention, the ends l5 may be drawn out from orpushed in toward the filler 6, limited by the distance of travelpermitted by the loops on the rods l3, which is the distance between theadjacent pairs of rods 8 as shown by broken lines in Fig. 1. As bestshown m n-1g. 2, the loops and horizontal wires are on one side of thevertical wires 8 leaving the other side planar between the frame to fitclosely against a similar supporting surface on door or 55 window. Therods I 3 are locked to the rods '1 by a clamp'zLtlghtened by a screw 22as shown in Fig. 1.

While} have herein shown and described my invention in the oneparticular form, it is obvious at each end of the horizontal series anda plurality of intermediate vertical rods between the endrods, all ofsaid rods being rigidly. attached at their intersections, rails securedto the top and bottom edges of the filler, rod extensions for thehorizontal rods, each looped at its inner end around an adjacenthorizontal rod and slidable thereon between a pair of intermediatevertical rods, a strip looped over the rod extensions and adjacenthorizontal rods and fastened at the ends of the loops to the endvertical rods, and a vertical member to which the outer ends of the rodextensions are fastened.
